I recently attended a talk by Dr. Ravi Gomatam on 'quantum reality', where the speaker suggested, that conservation of energy is not a fundamental law, and is conditional, but the conservation of information is fundamental. What exactly is the meaning of information? Can it be quantified? How is it related to energy?
If one measures lack of information by the entropy (as usual in information theory), and equates it with the entropy in thermodynamics then the laws of thermodynamics say just the opposite: In an isolated system, energy is conserved wheras entropy can be created, i.e., information can get lost.
The main stream view in physics (aside from speculations about future physics not yet checkable by experiment) is that on the most fundamental level energy is conserved (being a consequence of the translation symmetry of the universe), while entropy is a concept of statistical mechnaics that is applicable only to macroscopic bodies and constitutes an approximation, though at the huma scale a very good one.
